The results of the experiments conducted on various aspects of its cultivation are summarized briefly as under. In order to evaluate a good source of substrate for quality spawn production, jowar grain was found as best spawn substrate followed by wheat grain in respect of colour, texture of myceium and yield, though highest number of sporophores recorded by the use of ragi grain based spawn. Amongst the four species of Pleurotus, superiority of P. flabellatus was observed as compared to other species. Spawn raised on paddy straw mixed with wheat and rice bran though required less time for spawn run but gave poor yield.. Storage of spawn in room and refrigerator showed different effect on mushroom production. Spawn stored upto 50 days at room temperature and upto 70 days in refrigerator yielded mushroom. In general storage durations reduced the quality of spawn. Fresh spawn was found to be superior in respect of number of flushes, sporophores and yield of P. flabellatus followed byEnglishThesis
